The Wavesat 118/13 is a compact loudspeaker with extremely well-behaved sound dispersion and other very good sonic properties at a low price. Bernd Timmermanns has developed this closed speaker. The Wavesat 118/13 is home to a 13 mm Wavecor dome, the TW013WA01, and the mid-bass unit WF118WA06.
We warmly recommend this loudspeaker.
Its crossover consists of a low-pass and a high-pass branch each of second order, i.e. with a slope of 12 dB per octave.
We see a very even on-axis frequency response from 100 Hz to 20,000 Hz. The decay spectrum (waterfall diagram over frequency) is exemplary, free of any disturbing resonance above 2000 Hz. At 90 dB and 1 m, non-linear distortions remain below 0.4 % almost everywhere above 1000 Hz.
We recommend a subwoofer like Little Roy with passive crossover (100 Hz cut-off frequency).

The high-end kit contains Mundorf MCAP polyethylen foil capacitors. The coils are baked varnish coils for diminishing the microphonics effect. Current flowing through the coil creates a magnetic field which on itself sets the reel of wire in motion. That motion induces a voltage in the coil which adds itself to the original signal.

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).
If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit:
EUR 5,90 excl. VAT: € 4.96 / $ 5.70
We recommend one board per standard kit (two boards for a speaker pair)
We recommend two boards per hig-end kit (four boards for a speaker pair)
If you use WaveSat 118/13 together with a subwoofer, an additional high-pass filter should be applied.
